Symptoms

Some AD Query options require AD Group or AD PSO cache.The options are: "fetch nested groups", "fetch primary group" or any password management option.
Starting from APM 11.5.0, a cache is associated with a server object, so there is no way to build a cache using a user's credentials. If administrator credentials are not specified for the associated AAA AD Server object, then cache initialization fails silently.

Impact

It is not obvious why cache initialization failed.

Conditions

A feature that requires a cache is configured for AD Query.

Workaround

None

Fix Information

Now if cache init failure occurs, an error message is logged into /var/log/apm logfile to explain the reason, which is administrator credentials required.
